<p>The present invention provides a rapid rig-up and rig-down pipe stand building and racking system that is capable of being retrofit to an existing drilling rig. In particular, the invention relates to a horizontal to vertical pipe delivery machine that is mountable to a drilling rig. The horizontal to vertical machine delivers sections of pipe to a pair of drilling rig mounted elevators. The elevators receive and vertically translate the sections of pipe. A power tong may be used to make connections between the sections of pipe to form a pipe stand, and may also break the connections of the pipe stand. A drill floor mounted pipe racking system receives the connected drill pipe from the elevators. A pipe racking system that may be used in conjunction with the stand building system is capable of controlled, rapid, and precise movement of multiple connected sections of pipe.</p> |
